EMILE JOSEPH PEGLER, OF NEVI YORK, N.;

TRANSPARENT REFRIGERATOR.

Application filed March 23, 1916,

To all whom t may concern lie it ltnown that l. lCniLu Jost-:rn Puo- Lnn. a citizen ot' the United States, and a resident o'l5 the city ot New York, in the eounty and State ot' New York, ha ve invented new and Improved Transparentl\ei1'if3;- crators, olI which the following is a full, clear, and exact specilieation.

'lhis invention relates to improvennnts in display refrigerators; and an object ot this invention'is to provide a reirig'eratoi.' of which even the transparent parts are entirely insulated.

The show windows andglass casings hitherto used t'or the display ot' perishable loodstufls are neither sanitary nor economieal. Then in spite ot the lact that these windows and casings consume more ice or revtrigcrating' fluid than an ordinary iceboX with double wooden walls and saw-dust insulation therein, still 'it is dillicult to keep in simple glass easing's an even temperature at such a low degree. as the perishable `t'oods would require or where nieatis stored away every night in a cold vaultland in the daytime hung up along the walls'for display thus exposed to the market atmosphere, however it could be kept coi'istantly in an in sulated display refrigerator.

rl `he new display refrigerator, having no surlaee which would be not insulated, lullils a vital sanitary necessity.

rlhis invention consists olE construction,

arraiigement and combination .ot paris designed to produee display refrigerators with a transparent insulation which. is huilt up ot double glass walls containing a liller o'l water therein. or any transparent liquid. `Water is a poor heat eomluetor. and of ,greater density than othei; insulation 1natters as mineral wool, saw dust and the like; butin spite ol the favorable qualities -il` water as means for transjnirent' insulation, it has never before been utilized 'tor this purpose.

The way in which the foregoing obieets are attained in the most practical and simple manner is deseribed hereinafter with reference to the accolnpaiiying drawings in whieh similar characters denote eorrespomling parts throughout the several views and in which- Figure l is a view in perspective of a Specification of Letters Patent.

The refrigerator illustrated in Fig. l coniprises a suitable rectangular reeeliitaele hav ing an outer shell a. mounted on a base 7). This shell o is built up of glass sheets like c, el, c'- secured water-tight to metal .angles of which is formeel the iframe-work (i, (Z2. One side et' shell e. is partly out away in the drawing' to show that there is within a simi* lar inner shell al built of glass sheets like c, c" secured water-tight to the metal angle 'framing d5. Said inner shell is separated from the outer shell by an interval oi a few inches7 t? ne side and top surfaces of the shells thus kept in parallel spaced relation there is termed between both shells a anda1 a uniform sliaee. as f which has a watertight metal bottom e securely resting on the top ot base Z as a. lining thereon. At the top of the outer shell a two small holes g and f/1 are drilled through metal angle al and the corresponding edge of glass sheet el; the space between the outer and inner shells ma) be filled by a transparent lluid. like clear water. poured through one of the small holes, the other hole then serving to permit the escape of air. These outer and inner shells a and ri. containing the water filler between them, forni the walls of this refrigerator, thus -havin hr at each surface a transparent insulation, except at the bottoin, referred to hereinafter.

As show n in Fig. 3, the base is provided with a top portion it which is designed to carry the contents of the refrigerator as a bottoni thereof; this top portion /i is a sinkable platform, not connected to the immovable top portion 71.1 which surrounds the said sinkable platform li like a door-frame, and both are insulated h v a non-transparent iliaterial as shown in Fig'. 3. At a side- 'all of base L in Fig. 1 there is one leaf of a hinged door z' which consists of two leaves, one of which is broken away in the drawing with a part of its frame7 in order to disclose the interior of base which serves as a shaft j for the sinkingl of the platform i. 'lhe said door if allows a free access to the platform t when it is lowered to the bottom of shaft for the purpose to put on it the contents to he exhibited. The operation of lowering' and lifting of this platform /L niit'ht be performed by hand and by any simple structure of some approved type adapted to sink area platforms, ashlifts and the like. and which consists inthe pres-eut instan/fe, for purposes of illustration, of the said shaft j containiinglr at each of the four corneis one set of pulleys. comprising two toothed wheels like l and Z1 near the wall of the sha ft y' one above the other so far apart as the space allows, and connected vertically by a spoked chain 7u. Opposite to said wheel Z is wheel Z2, both connected horizontally by a common axis n which extends from wall to wall of the shal't and is rotatable in the bearings m. '.l`he upper wheel Z1 is similarly connected by the upper axis n.1. tonseqnently if one wheel like ll is turned it turns wheel l by chain le, and wheel l? by axis n, this mutual movement is transmitted to the other two sets of pulleys at the opposite end of shaft i'.by wheel Z which is located on the inner end of the rotating axis In, and turns the horizontally1 disposed chain le thereon7 which is similarly connected to axis n3; thus a ria-iproeating rotation of the `four sets of pulleys is produced when one wheel is turned by hand through the crank O `vhich is shown outside of the shaft7 being an extension of an upper axis like nl, but if not in use can be taken ofi'. To the vertically rotating chains l.; and Inl is fastened a horizontally disposed steel bar 1], and in the same way is a sini'ilar bar q1 secured to the chains /U'i and L, these bars and r/1 carry the sinkahle platform It. A removable plug` y; goes through the wall of base l) into the `of two glass sheets like c7 and el" shown in Figs. 5 and (l, spaced a few inches apart in parallel relation and framed water-tight by a metal channel T, is in itself an independent rectangular flat block v and w* enveloped in the wooden frame e and e2. blocks .fr and e" are filled with clear water before set in the woodwork 'u and yU`. 1f the panels are very large and the glass sheets c" and c comparatively too thin, the horizontal block w1 can be left unfilled. ()pposite to the front there is the rear wall ef which includes'the hinged door t; as shown in horizontal section in Fig, 5 and in vertical section in Fig. t3, thisdoor t and the bottoin u are insulated by some non-transparent matter.

Fija'. 7 represents the partial elevation of a display refrigerator of which the front is transparent comprising sliding doors L and mullions or immovable panels N of similar appearance and alternatingly located, each of these doors and panels consists of a rec tangnlar inner frame 'l"l built of metal channel, which holds apart the outer glass sheet t and the inner ,glass sheet. (1 fastened lhereto watertight. 'l'he frame T2 and the edges ol' the glass sheets (l and (ll are securely covered by the outer metal channel-l'ranie l. t the upper end. of each ol' the doors li and panels N there are sniall holes 'r/L' drilled in the webs ol' the inelal channels 'l`2 and ll l'or the purpose of filling lh`e space l'ormed between the glass sheets and with clear water of a teinpei'aliire of about tlt) degrees, preferably after the doors are put in place. 'lo the bottom ol' door li are 'fastened two small supporting` wheels il rn' nine in the steel groove lo' adapted for this purpose on the top cover of base ll, A\bo\'e the doors ex-l lcnds horizontally the 2guide il inade of a flat steel bar to lit the ,groove ofa small wheel l which rollsl on it; the axis olI this groove/.l wheel l is the two legged metal hanger lf olwhich both legs are secured to. the 'upper end ol door li. ly this means the door li. when moved, slides easily in spite of its size andweicht.

The said Fig. l() is a wooden display refrigerator having a front of which' the upper part y is vertical,l with transparent panelsw therein to be opened as hinged doors; the lower front is inclined and contains transparent panels irl which are pivoted doors. The construction ot' traiispai'ent insulation of these panels is shown in vertical section in Fig. l1 being an enlarged partial detail of quirements ot particular uses; but in each" of these toi-ins vthe principle, which is the v basis of this invention, is strictly kept, to produce transparent. parts which are insu# lated, by employing the saine elements, and thereby attain the same results.
